ADJUSTABLE REC'LINING CHAIR.

Application filed April 29, 1922. Serial 1110. 557,399.

T all whom it may concern:

Be it known that l, FRANK lP. HALL, a citizen of the United States, residing at Mont Alto, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Reclining Chairs, of which the following is a specification.

My invention relates to chairs of the folding type and one object of the invention is to provide a chair of this class which has its seat adjustable both as to height and depth and its back adjustable in angular position.

Another object of the invention resides in the fact that the chair may be folded substantially flat in order to take up as little room as possible when not in use.

Other objects and advantages will be evident from the following description and the accompanying drawings, in which:

Figure 1 is a perspective view of the chair ready for use,

Figure 2 is a sideelevation showing the chair folded,

Figure 3 is a side elevation showing the chair erected, and

Figure 4 is a longitudinal sectional view of the chair also in erected position.

The principal parts of the chair are three frame structures which-may be designated as the front leg frame 10, the rear leg frame 11, and the foot rest frame 12. In addition, the chair is provided with a pair of arm rests 13, back supports 14, and a prop at the end of the foot rest frame 12.

The front leg frame 10 comprises a pair of parallel side bars 16 connected at their lower ends by a cross rod 17 The upper end of the frame is similarly connected by means of a cross rod 18 in close proximity to which a second cross rod 19 is situated, having only a very narrow space between them. A clamping bolt 20 is rovided for each of the side bars 16 a short distance above the lower end of the frame and on the inner end of each clamping bolt is secured an arm 22 connecting the rear ends of these arms. About midway between the upper end of the frame and the bolt 20 is secured a pair of pivots 23 upon which is hinged the supporting frame 14 which also consists of a pair of side rods 24 connected at their free ends by means of a cross rod 25. The supporting frame is attached on the outside of the front leg frame and outside of the side rods 24 of the supporting frame, the arm rests 13 ahe pivoted as at 26, on the supporting frame. The arm rests 13 project forwardly and are preferably provided with fiat boards 27. On the inside of the arm rests 13 are hinged links 28 which, at their lower ends, are pivoted on the clamping bolts 20.

The rear leg frame 11 is constructed in a manner similar to the front leg frame and consists of side bars 29 connected at their rear ends by means of a rod 30 and at their front ends by means of a similar rod 31, and a third cross rod or dowel 32 connects the side bars 29 about midway between the ends thereof. A longitudinal slot 33 is formed in each of the side bars 29 and has an approximate length of a third of the distance between the cross rod 31 and the dowel 32. These slots 33 receive the clamping bolts 20, each of which is provided with a thumb nut 34 for tightening the arms 21, the side bars 29 of the rear leg frame, the side bars 16 of the front leg frame, and the links 28 on the bolts. Spaced apart along the upper edges of the side bars 29 of the rear leg frame area number of notches 35 which are intended to engage the cross rod 25 at the lower end of the supporting frame 14.

The seat and back rest proper are formed from a length of canvas 36 which, at its lower end, is attached to the cross rod 22 on the arms 21. From this cross rod, the canvas is taken rearwardly around the dowel 32, thence underneath and forward to the cross rod 31, and back again over the same and around the top cross rod 18 and between the same and the second cross rod 19 and its upper end is folded over and secured to a rod 37. A short strip of canvas 38 is also secured to the cross rod22 on the arms 21 and is sewed fast to the middle of the long canvas 36, as at 39.

The foot rest frame 12 is also constructed from a pair of side bar's'39 which are hinged on a rod 40 secured in the forward end of the rear leg frame 11. At the free end of the foot rest is another cross rod 41 back of which is'a third cross rod 42, upon which is hinged the prop 15. This prop is also built in the shape of a frame having side bars 43 and a rod 44 connecting their free ends. Between the cross rods 40 and 41 in a suitable pair of the notches 35 on the ent of the seat-and back canvas 36.

Inlsetting'up the chair, the front leg frame 10 and the rear leg frame 11 are first position such, for inswung in a suitable stance, as shown in F rod 25 of the supporting frame 14 resting rear leg frame. The clamping bolt is now made to slide along theslot 33 until a suitable length of seat is obtained when the clampin nuts 34 are drawn up tightly. This wil then rigidly secure the links 28 of the arm rest 13, the front leg frame 10, the rear leg frame 11, and the arms 21, positioned in the order mentioned from the outside in. In shifting the clamping bolt 20 back and forth in the slots 33, the canvas 36 will be drawn around the cross rod 31'and dowel 32 a similar amount actuated by the cross rod 22 and arms 21, and the slackness of the canvas 36 where it forms the back and seat is taken up by pulling on the rod 37, when the canvas will be drawn up between therods 18 and 19 and rigidly held in any suitable position by the weight of the reclining body in the chair.

It will now be evident that adjustment is provided not onl for the height of the seat but also for its epth as well as for the inclination of the back of the chair.

When the chair is not in use, it is preferably folded into flat position, as indicated in Figure 2 and this is done as best illustrated in Figure 3, where the arrows indicate the direction of swinging the different parts. The operations in that case will be: first, to lift the supporting frame 14 out of the notches 35 in the rear leg frame and swing it upwardly as indicated by the arrows A and B, when the arm rests 13 will also be moved in the direction of the arrows C and D. The thumb nuts 34 are now loosened and the front leg frame 10 folded against the rear leg frame 11 in the direction indicated by arrows E and F, which will then compel the parts 27 of the arm rests 13 to lie flat along the forward edges of the front leg frame 10. F inall the prop 15 is swung inwardly, as indicated by arrow G and the foot rest frame 12 swung upwardly, as indicated by arrow H in Figure 3. The parts will then be positioned as seen in Figure 2,

gure 4, with the cross' adjustably held when the chair may be put away in a closet where it will occupy very little space.

Having thus described the invention, what is claimed as new is:
